Director Sofia Coppola attends the "The Beguiled" photocall during the 70th annual Cannes Film Festival at Palais des Festivals on May 24, 2017 in Cannes, France.

The Cannes Film Festival awarded its coveted Palme d'Or award to Ruben Ostlund's "The Square" on Sunday, while Sofia Coppola became only the second woman to win the best director award.

"Oh my god! OK," the Swedish filmmaker exclaimed after he bounded onto the stage to collect the prestigious Palme.

Coppola won best director for "The Beguiled," her remake of Don Siegel's 1971 Civil War drama. The first — and until now only — female winner of the prize was Soviet director Yuliya Ippolitovna Solntseva in 1961.

Dominic West, Elisabeth Moss and Claes Bang star in "The Square." Bang plays the curator of an art museum, who sets up "The Square," an installation inviting passers-by to acts of altruism. But after he reacts foolishly to the theft of his phone, the respected father of two finds himself dragged into shameful situations.
